Taconic TRF-45 2-Layer 0.9mm Immersion Gold PCB – Satellite & GPS Antenna

1.Introduction to TRF-45 PCB

The TRF-45 laminated materials represent a new generation of low-loss, thermally-stable laminated material from Taconic Advanced Dielectric Division. TRF-45 is woven-glass reinforced for enhanced dimensional-stability and coupled with Taconic's expertise in ceramic technology. It exhibits low and consistent Z-axis expansion across a wide range of temperature including and up to soldering conditions.

TRF-45 can be sheared, drilled and plated using standard methods for PTFE woven fibre-glass materials.

This 2-layer rigid PCB is constructed entirely with TRF-45 as the core material, providing excellent signal integrity, thermal stability, and low-loss performance for demanding RF and antenna applications.

2.Key Features of TRF-45 PCB

• Low-loss ceramic-filled PTFE

• Stable Dielectric constant (Dk) of 4.5 ± 0.15 at 10GHz over temperature and frequency
